Presence of Methane on Pluto confirmed: NASA

Pluto_for_wikiWashington: NASA’s New Horizon probe — set for a Pluto flyby on July 14 — has confirmed that there is frozen methane on Pluto’s surface.

The Earth-based astronomers first observed Methane on Pluto in 1976.

“We already knew there was methane on Pluto but these are our first detections,” said Will Grundy, team leader with the Lowell Observatory in Flagstaff, Arizona.

Soon, we will know if there are differences in the presence of methane ice from one part of Pluto to another, he added in a statement.

New Horizons is now about 16 million km from the Pluto system – around 4.75 billion km from the Earth.

Methane was detected by a team of ground-based astronomers led by New Horizons team member, Dale Cruikshank of NASA’s Ames Research Center, Mountain View, California.

The detection was made possible with the help of  the infrared spectrometer on New Horizons spacecraft.

Methane is an odourless, colourless gas that is present underground and in the atmosphere on the Earth.

On Pluto, methane may be primordial, inherited from the solar nebula from which the solar system formed 4.5 billion years ago.

Just hours after its flyby of Pluto on July 14, the spacecraft will observe sunlight passing through the planet’s atmosphere, to help scientists determine the atmosphere’s composition.

“It will be as if Pluto were illuminated from behind by a trillion-watt light bulb,” noted New Horizons scientist, Randy Gladstone.

The spacecraft is healthy and all systems are operating normally.

“We are really on the final path. It just gets better and more exciting every day,” said project manager Glen Fountain. (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.

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.
