NASA fixes Mars lander by hitting it with a shovel


(CNN)NASA may have a multi-billion dollar budget and some of the most advanced technology in the world, but when the Mars InSight lander got into a spot of bother, scientists came up with a charmingly rudimentary fix for its space technology: Hit it with a shovel.
The trouble started when a heat probe, known as the "mole," did not manage to dig into the red planet as planned last year.
This was due to a lack of friction, which the probe needs in order to burrow into the soil, according to a NASA statement.
After several months, the NASA InSight Twitter account outlined its strategy as "giving it a push with my robotic arm."
And the team has now announced that progress is being made.
Now the team hopes the mole can get on with measuring heat under the surface of the planet, providing information that will help scientists work out how Mars, and all rocky planets, were formed.
InSight, or Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a two-year mission to explore a part of Mars that we know the least about: Its deep interior.
The suite of geophysical instruments on InSight sounds like a doctor's bag, giving Mars its first "checkup" since the planet formed. Together, those instruments take measurements of Mars' vital signs, like its pulse, temperature and reflexes — which translate to internal activity like seismology and the planet's wobble as the sun and its moons tug on Mars.
Since landing on Mars in November 2018, the InSight mission has been taking selfies, providing daily Martian weather reports and hearing strange sounds.
It has also recorded evidence of seismic activity, including 174 seismic events across Mars -- and 20 events with a magnitude of three or four.
Evidence of seismic activity on Mars that surprised the NASA team was part of a suite of six studies, published in February.

You may soon be able to ride to the edge of space from Alaska in a Balloon Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune A company wants to use an advanced balloon to fly customers from Earth’s surface in Alaska to the highest reaches of the planet’s atmosphere. Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune,  The Anchorage Daily News  reported on Sunday. The balloon rides will be manned by a flight crew taking eight passengers in a pressurized capsule suspended beneath a hydrogen balloon the size of a football stadium. Each passenger could pay an estimated $125,000 for a six-hour journey. Mark Lester, CEO of Alaska Aerospace Corp., said the high-altitude rides will be available from Kodiak in a few years and will ...

Committee recommends review of planetary protection policies

Committee recommends review of planetary protection policies WASHINGTON — The NASA Advisory Council has recommended that NASA review its existing planetary protection guidelines to balance the needs of science and exploration, an effort that could set the stage for a similar revision at the international level. The council, during a two-day meeting at NASA Headquarters Dec. 10–11, adopted a recommendation calling on NASA to establish an interdisciplinary committee of experts to review the agency’s current requirements for preventing contamination of other worlds by NASA spacecraft as well as any contamination of the Earth by materials brought back from those worlds. “NASA should establish a multidisciplinary task force of experts from industry, the scientific community, and relevant government agencies, to develop U.S. policies that properly balance the legitimate need to protect against the harmful contamination of the Earth or other celestial bodies with the scientific, social, and e...

Surprise! There's more water on Jupiter than anyone thought

Surprise! There's more water on Jupiter than anyone thought Jupiter  appears to have more water than anyone expected. Newly released data from  NASA's Juno probe shows that water may make up about 0.25% of the molecules in the atmosphere over Jupiter's equator. While that doesn't sound like much, the calculation is based on a prevalence of water's components, hydrogen and oxygen, three times more than at the sun. The new measurements Juno obtained are much higher than a previous mission suggested. The surprise result has scientists delving deep again into results from  NASA's Galileo mission to Jupiter , which obtained drier results in 1995 when engineers deliberately threw the spacecraft into Jupiter's atmosphere. (Galileo was low on fuel and NASA didn't want to take the chance, even if it was a slight one, of the spacecraft accidentally crashing on a potentially habitable icy moon.) Reconciling the results from Galileo and Juno is key for sc...
