NASA and SpaceX explore using Dragon to send Hubble back to its initial position

Posted by in category: space travel

NASA and SpaceX are undertaking a feasibility study.

The Hubble Space Telescope could one day be serviced by a private SpaceX spacecraft called Dragon, according to an article published by Space.com


Jensen further added that a Dragon Hubble mission wouldn’t necessarily need to be crewed. The study might point the way to an uncrewed mission with Dragon or even a different aircraft.

NASA is working with SpaceX to explore a private mission to extend the life of the Hubble telescope

Posted by in categories: Elon Musk, space travel

SpaceX and billionaire astronaut Jared Isaacman are teaming up with the National Aeronautics and Space Administration to study whether a private mission could extend the life of the famed Hubble telescope.

NASA signed an agreement with Elon Musk’s company and the Polaris Program, which Isaacman leads, to study the possibility of using a SpaceX spacecraft to dock with the telescope and change its orbit in an effort to further its lifetime, the parties announced Thursday.

NASA’s science chief Thomas Zurbuchen said during a press call that SpaceX approached NASA with the idea “a few months ago.”

Space telescopes capture asteroid slam with striking clarity

Posted by in category: space travel

CAPE CANAVERAL, Fla. (AP) — The world now has stunning new photos of this week’s asteroid strike, the first planetary defense test of its kind.

NASA on Thursday released pictures of the dramatic event taken by the Hubble and Webb space telescopes.

A few hours later, SpaceX joined NASA in announcing that they’re studying the feasibility of sending a private mission to Hubble, potentially led by a billionaire, to raise the aging telescope’s orbit and extend its life.

NASA, SpaceX to Study Hubble Telescope Reboost Possibility

Posted by in categories: government, space travel

NASA and SpaceX signed an unfunded Space Act Agreement Thursday, Sept. 22, to study the feasibility of a SpaceX and Polaris Program idea to boost the agency’s Hubble Space Telescope into a higher orbit with the Dragon spacecraft, at no cost to the government.

Jupiter is coming its closest to Earth in decades

Posted by in category: space travel

The gas giant Jupiter is coming the closest it has come to Earth in 59 years this Monday and will be particularly visible because it coincides with another event called opposition.

When in opposition, a planet is on the opposite side of Earth from the sun, so you could draw a straight line from the sun to Earth to Jupiter, all in alignment. Jupiter’s opposition happens every 13 months. Looking from the Earth, when the sun sets in the west, Jupiter will rise in the east, directly opposite. During opposition, planets appear at their biggest and brightest.

Separately, Jupiter is coming closer to Earth than it has since 1963. Because of Earth’s and Jupiter’s differing orbits around the sun, they don’t pass each other at the same distance each time. When it’s closest on Monday, Jupiter will be about 367 million miles from Earth, according to NASA. At its farthest, it’s 600 million miles away.

Multi-Stage Ion Thruster Holds Exciting Promise

Posted by in category: space travel

Anyone who’s looked into high-voltage experiments is likely familiar with ion lifters — spindly contraptions made of wire and aluminum foil that are able to float above the workbench on a column of ionized air. It’s an impressive trick that’s been around since the 1950s, but the concept has yet to show any practical application as the thrust generated isn’t nearly enough to lift a more substantial vehicle.

It’s a bit early to suggest that [Jay Bowles] of Plasma Channel has finally found the solution to this fundamental shortcoming of electrostatic propulsion, but his recently completed multi-stage ion thruster certainly represents something of a generational leap for the technology. By combining multiple pairs of electrodes and experimentally determining the optimal values for their spacing and operational voltage, he’s been able to achieve a sustained exhaust velocity of 2.3 meters per second.
