SpaceX, NASA move ahead with second Dragon launch pad

Makes Statement0 Comments

SpaceX and NASA officials confirm they are moving forward with plans to modify the LC-40 launch pad to support Crew and Cargo Dragon missions. SpaceX began studying the possibility of modifying the pad earlier this year, after NASA raised concerns about the risks posed by plans to operate its next-generation Starship rocket out of LC-39, which is currently used for Dragon missions. Likely modifications include building a new crew access tower, crew access arm, escape system (39A uses baskets and ziplines), and an on-site bunker for astronauts.

‘Impossible engine’ works in tests

Makes Statement0 Comments

NASA conducts more tests of its ‘impossible engine’, and the first public update in months suggests fuel-free thrusters do work — but they don’t know why. Paul March, one of the top engineers working the EM Drive thruster at the Eagleworks Laboratory at the Johnson Space Center in Texas, posts the update on the NASA Spaceflight forum in response to a claim the unaccounted thrust is generated by something known as the Lorentz force, a force that is exerted by a magnetic field on a moving electric charge. March says his tests prove this is not true.

I will tell you that we first built and installed a second generation, closed face magnetic damper that reduced the stray magnetic fields in the vacuum chamber by at least an order of magnitude and any Lorentz force interactions it could produce, and yet the anomalous thrust signals remain.

March says they have managed to remove some of the errors from earlier tests – but still found signals of unexplained thrust.

15 years continuous habitation

Breaks Record0 Comments

The ISS celebrates 15 years of continuous human habitation. In that time over 220 astronauts, cosmonauts and fee-paying space tourists have visited the station. NASA:

It is the blueprint for global cooperation. One that enables a multinational partnership and advances shared goals in space exploration.

Water and ice found

Makes Statement0 Comments

Pluto haloNASA says that Pluto has traces of water and ice on its surface. Red-colored frozen surface water is confirmed by combining spectral infrared and visible light data taken by two of New Horizons’ image sensors. The agency also releases a picture of Pluto’s blue sky, which is caused by tiny, sunlight-scattering particles in the atmosphere. Those particles probably begin as molecular nitrogen (which Pluto is constantly emitting) and other trace gases.

Charon detailed images

Makes Statement0 Comments

NASA releases detailed photos and a flyover animation of Charon, taken by New Horizons when it made its close flyby of Pluto on July 14. Scientists say they expected to find a long-dead world pocked with craters, but instead the surface plays host to mountains, a red north pole and a host of other geological features including a canyon more than 1,000 miles wide that stretches across the moon’s Pluto-facing side, and perhaps along the far-side of the world. That canyon is probably four times longer than the Grand Canyon is on Earth, and twice as deep in some places.

We thought the probability of seeing such interesting features on this satellite of a world at the far edge of our solar system was low, but [we] couldn’t be more delighted with what we see.

Flowing water found on Mars

Makes Statement0 Comments

NASA says ‘dark finger-style’ marks that change with the seasons and were first spotted in 2011 by Ojha, using images taken by the Mars Reconnaissance Orbiter, are signs of water flowing under the surface of Mars. Ojha investigated the composition of these seasonal flows by studying their infrared wavelengths. In each location researchers found the presence of hydrated salts during the times when the flows are most extensive – suggesting a link between the two. In particular, evidence was found for sodium perchlorate, magnesium perchlorate and magnesium chlorate which are thought to be left behind when brine evaporates. Ohta:

The only thing we can really assert is that the places we’re finding are probably more habitable than the rest of the planet, which is bone dry.

Pluto hi-resolution images

Makes Statement0 Comments

Pluto New Horizons Rippling Terain imageNASA releases high resolution New Horizons images of Pluto’s surface that show rippling terrain that stretches many hundreds of km. Team member:

It looks more like tree bark or dragon scales than geology. This’ll really take time to figure out; maybe it’s some combination of internal tectonic forces and ice sublimation driven by Pluto’s faint sunlight.

The ripples are part of a 70MB image (link) that combines images from the probe’s Ralph/Multispectral Visual Imaging Camera, that combines blue, red and near infrared (NIR) images.

Next flyby target selected

Makes Statement0 Comments

NASA determines the next likely target destination for a flyby by New Horizons, a small object in the Kuiper Belt called 2014MU69. It orbits almost a billion miles away from Pluto. A full proposal about the mission will be evaluated by NASA experts before the go ahead is officially given. NASA Science Mission Directorate Chief Grunsfeld:

Even as the New Horizon’s spacecraft speeds away from Pluto out into the Kuiper Belt, and the data from the exciting encounter with this new world is being streamed back to Earth, we are looking outward to the next destination for this intrepid explorer. While discussions whether to approve this extended mission will take place in the larger context of the planetary science portfolio, we expect it to be much less expensive than the prime mission while still providing new and exciting science.

Eat lettuce grown in ISS

Makes Statement0 Comments

NASA astronauts on the International Space Station eat red romaine lettuce, which they freshly harvested from the orbiting lab’s vegetable plant growth system. The space garden snack marks the first time NASA had cleared its astronauts to eat what they grew. Before eating, they clean the lettuce with citric acid-based sanitizing wipes.

Lindgren: That’s awesome
Yui: I like that
Kelly: It tastes like arugula

The three save a few leaves for their Russian cosmonaut crewmates, two of whom are out on a spacewalk. Half of the harvest is frozen on the station so it can be returned to Earth for scientific analysis.

NASA anticipates greater discoveries

Makes Statement0 Comments

Speaking before the House Committee on Science, Space and Technology, Stern says scientific information gleaned from the New Horizons mission to Pluto is “revolutionizing” what they know about the icy dwarf planet, predicting that even greater discoveries lay ahead.

With only 5% of data on the ground, we all feel we need to fasten our seat belts for the next 95%.

It will take 16 months for all the collected data from New Horizons to be transmitted to Earth. Scientists say the mission demonstrates this need for further planetary exploration.

Now is the time to accelerate, not curtail, the pace and scope of our nation’s solar system exploration program.

EMP-Earthquake link challenge

Makes Statement0 Comments

A NASA challenge is looking for evidence to support a theory that electromagnetic pulses (EMP) may precede an earthquake, potentially offering a warning to those in a temblor`s path. A two-week algorithm challenge seeks to develop new software codes to search through data and identify electromagnetic pulses that may precede an earthquake. Contestants will be provided with electromagnetic signal data collected over three-month duration from multiple sensors in the proximity of past earthquakes. NASA:

Developing a reliable approach that can separate potential earthquake-induced electromagnetic pulses from the myriad of natural and anthropogenic sources has been a significant challenge. We look forward to seeing the innovative ideas from this competition and learning more about this controversial phenomenon.

Heart shape sharper image

Makes Statement0 Comments

NASA releases a sharper image of Pluto showing that the left half of the Tombaugh Regio heart region is different than the right. The left half is more filled in. Scientists believe some process, possibly wind, is blowing material from the left half to the right half.

Our interpretation is that material in the right lobe — the source for that material — is coming from the western [or left] lobe.

NASA releases a photo which suggests that glaciers are flowing on Pluto’s surface in the region of Sputnik Planum. Scientists believe the ice is made of nitrogen, carbon monoxide and methane.

To see evidence of recent geological activity is simply a dream come true. The appearance of this terrain, the utter lack of impact craters on Sputnik Planum, tells us that this is really a young unit.

Eclipses the sun

Makes Statement0 Comments

Backlit by the sun, Pluto’s atmosphere rings its silhouette like a luminous halo in this image taken by NASA’s New Horizons spacecraft around midnight EDT on July 15. This global portrait of the atmosphere was captured when the spacecraft was about 1.25 million miles (2 million kilometers) from Pluto and shows structures as small as 12 miles across. The image, delivered to Earth on July 23, is displayed with north at the top of the frame.NASA releases a photo of Pluto eclipsing the sun showing a haze in Pluto’s atmosphere which extends at least 160 km (100 miles) above the surface.

This is one of our first images of Pluto’s atmosphere. [It] stunned the encounter team. For 25 years, we’ve known that Pluto has an atmosphere. But it’s been known by numbers. This is our first picture. This is the first time we’ve really seen it. This was the image that almost brought tears to the eyes of the atmospheric scientists on our team.

Pluto and Charon’s natural color

Makes Statement0 Comments

 Pluto and its largest moon Charon are seen in their natural color in this spectacular image by composite of images from NASA's New Horizons spacecraft taken during its July 14, 2015 flyby. In this image, the north poles of both Pluto and Charon NASA releases this photo which shows Pluto’s reddish color and Charon’s gray tone. Scientists think Pluto’s red color is the result of particles created in its atmosphere, through methane’s interaction with UV light. The particles stick together, growing heavier, and eventually rain down on the surface. Observations show that Charon does not have much of an atmosphere.

For now, all that we can say is, it’s a much more rarefied atmosphere [than Pluto’s]. It may be that there’s a thin nitrogen layer in the atmosphere, or methane, or some other constituent. But it must be very tenuous compared to Pluto — again, emphasizing just how different these two objects are despite their close association in space.

Earth-like world discovered

Makes Statement0 Comments

NASA’s Kepler mission discovers Kepler-452b, the first near-Earth-size planet in the habitable zone around a sun-like star. 425b is located about 1,400 light years away in the Constellation Cygnus, orbiting a star slightly brighter than the sun. The planet is about 60% larger than Earth and about 1.5 billion years. There is no evidence that it has an atmosphere.

We can think of Kepler-452b as an older, bigger cousin to Earth, providing an opportunity to understand and reflect upon Earth’s evolving environment. It’s awe-inspiring to consider that this planet has spent six billion years in the habitable zone of its star; longer than Earth. That’s substantial opportunity for life to arise, should all the necessary ingredients and conditions for life exist on this planet.

Discovers second mountain range

Makes Statement0 Comments

A newly discovered mountain range lies near the southwestern margin of Pluto’s heart-shaped Tombaugh Regio (Tombaugh Region), situated between bright, icy plains and dark, heavily-cratered terrain. This image was acquired by New Horizons’ Long Range Reconnaissance Imager (LORRI) on July 14, 2015, from a distance of 48,000 miles (77,000 kilometers) and sent back to Earth on July 20. Feature as small as a half-mile (1 kilometer) across are visible. These frozen peaks are estimated to be one-half mile to one mile (1-1.5 kilometers) high, about the same height as the United States’ Appalachian Mountains. The Norgay Montes (Norgay Mountains) discovered by New Horizons on July 15 more closely approximate the height of the taller Rocky Mountains. NASA releases a photo showing another mountain range on the lower left edge of Pluto’s heart-shaped region. The peaks are about 1 to 1.5 km (0.5 to 1 mile) high, about the size of the Appalachians. The new range is just west of the region within Pluto’s heart called Sputnik Planum (Sputnik Plain) and some 110 km (68 miles) northwest of Norgay Montes. This newest image further illustrates the remarkably well-defined topography along the western edge of Tombaugh Regio.

There is a pronounced difference in texture between the younger, frozen plains to the east and the dark, heavily-cratered terrain to the west. There’s a complex interaction going on between the bright and the dark materials that we’re still trying to understand.

Nix and Hydra

Makes Statement6 Comments

Pluto's moon Nix (left), shown here in enhanced color as imaged by the New Horizons Ralph instrument, has a reddish spot that has attracted the interest of mission scientists. The data were obtained on the morning of July 14, 2015, and received on the ground on July 18. At the time the observations were taken New Horizons was about 102,000 miles (165,000 km) from Nix. The image shows features as small as approximately 2 miles (3 kilometers) across on Nix, which is estimated to be 26 miles (42 kilometers) long and 22 miles (36 kilometers) wide. Pluto's small, irregularly shaped moon Hydra (right) is revealed in this black and white image taken from New Horizons' LORRI instrument on July 14, 2015 from a distance of about 143,000 miles (231,000 kilometers). Features as small as 0.7 miles (1.2 kilometers) are visible on Hydra, which measures 34 miles (55 kilometers) in length.NASA releases photos of Pluto’s moons Nix and Hydra. Nix is about 42 km (26 miles) long and 36 km (22 miles) wide. Nix’s surface is a light gray with an area that is light red which scientists think might be a crater. Hydra is about 55 km (34 miles) long and 40 km (25 miles) wide and has at least two large craters.

Before last week, Hydra was just a faint point of light, so it’s a surreal experience to see it become an actual place, as we see its shape and spot recognizable features on its surface for the first time.
