NASA’s InSight Lands Safely on Mars

US shutdown delays space missions but NASA not grounded: Report,

Though NASA’s InSight landed safely on the surface of Mars, but the spacecraft sits about 4 degrees tilted, the US space agency said.

Early last week, InSight touched down on a lava plain named Elysium Planitia on the Red Planet.

The vehicle sits tilted slightly in a shallow dust-and sand-filled impact crater known as a “hollow”. But, InSight has been engineered to operate on a surface with an inclination up to 15 degrees, NASA said in a statement on Friday.

“The science team had been hoping to land in a sandy area with few rocks since we chose the landing site, so we couldn’t be happier,” said InSight project manager Tom Hoffman at NASA’s Jet Propulsion Laboratory (JPL) in California.

“There are no landing pads or runways on Mars, so coming down in an area that is basically a large sandbox without any large rocks should make instrument deployment easier and provide a great place for our mole to start burrowing,” he added.

Rockiness and slope grade factor into landing safety and are also important in determining whether InSight can succeed in its mission after landing.

According to the team, rocks and slopes could affect InSight’s ability to place its heat-flow probe — also known as “the mole” or HP3 — and ultra-sensitive seismometer, known as SEIS, on the surface of Mars.

But, a preliminary assessment of the photographs taken so far of the landing area suggests the area in the immediate vicinity of the lander is populated by only a few rocks.

Higher-resolution images are expected to begin arriving over the coming days, after InSight releases the clear-plastic dust covers that kept the optics of the spacecraft’s two cameras safe during landing.

“We are looking forward to higher-definition pictures to confirm this preliminary assessment,” said JPL’s Bruce Banerdt, principal investigator of InSight.

“If these few images – with resolution-reducing dust covers on – are accurate, it bodes well for both instrument deployment and the mole penetration of our subsurface heat-flow experiment.”

 Data downlinked from the lander also indicate that during its first full day on Mars, the solar-powered InSight spacecraft generated more electrical power than any previous vehicle on the surface of Mars, NASA noted.

Launched from Vandenberg Air Force Base in California on May 5, InSight will operate on the surface for one Martian year plus 40 Martian days, or sols — the equivalent of nearly two Earth years. InSight will study the deep interior of Mars to learn how all celestial bodies with rocky surfaces, including Earth and the Moon, formed. (IANS)

Spacecraft Test Runs into Serious Problems, Smoke All Over SpaceX in Florida

"Ensuring that our systems meet rigorous safety standards and detecting (issues) like this prior to flight are the main reasons why we test"

Thick plumes of smoke rose over a SpaceX facility in Florida during a test fire of a Crew Dragon spacecraft and the issue was serious, it could derail plans to fly astronauts aboard the capsule later this year, the media reported.

SpaceX, which was founded by billionaire businessman Elon Musk in 2002, said the craft was undergoing a “series of engine tests” at a facility in Cape Canaveral on Saturday, and something went wrong during the final stretch, CNN reported.

SpaceX will work with NASA to determine what caused the issue. No injuries were reported.

“Ensuring that our systems meet rigorous safety standards and detecting (issues) like this prior to flight are the main reasons why we test,” SpaceX said in a statement.

Crew Dragon is already overdue and more delays could make things tricky for NASA.

It was scheduled to conduct a key test of its emergency abort system in June. And its first crewed mission, which will carry astronauts Doug Hurley and Bob Behnken, was slated for July, though NASA recently said that timeline was under review.

NASA has also decided to ask the private sector to design and build a new generation of spacecrafts.

SpaceX and Boeing, which is building a vehicle called Starliner, were awarded contracts worth up to $2.6 billion and $4.2 billion, respectively, in 2014. Both capsules were supposed to start flying in 2017, but they have been hampered with delays.
