How long does it take to get to Mars?

If you wanted to travel to Mars, how long would it take? The answer depends on several factors, ranging from the position of the planets to the technology that would propel you there.  According to NASA, a one-way trip to Mars would take about nine months. If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back…

NASA wants your ideas to reuse trash and waste on a Mars mission

NASA just opened a challenge seeking ways to go to Mars and back with a minimum of wasted materials. The agency’s tournament lab, along with crowdsourcing platform HeroX, have launched a “Waste to Base” challenge looking for ideas to recycle trash, waste, carbon dioxide and foam packaging materials during a two- to three-year crewed Red Planet mission. Competitors have until March 15 to enter the challenge, and several prizes of up to $1,000 each will be awarded for novel ideas, out of a total purse of $24,000. The winner should…

James Webb Space Telescope marks deployment of all mirrors

NASA’s massive new observatory has notched another milestone. After nearly a full month in space, the James Webb Space Telescope, also known as JWST or Webb, is nearly at the end of its deployment work. The complicated series of deployments has seen the telescope transform from its tightly-folded launch configuration to what looks like a real observatory, although science observations remain months away. “Just in from the @NASAWebb team: All 18 primary mirror segments and the secondary mirror are now fully deployed!” NASA Administrator Bill Nelson wrote in a tweet…

Here’s how the James Webb Space Telescope is aligning its mirrors in deep space

The James Webb Space Telescope continues to fine-tune its mirrors to ultimately peer into the deep and distant universe. The telescope launched Dec. 25 with the 18 hexagonal segments of its primary mirror and its secondary mirror folded up and stowed so that the components would survive the rigors of liftoff. Now, the telescope is close to reaching its way to its deep-space destination and is starting to move those mirror segments into alignment. “Before launch, the mirrors were all positioned with the pegs held snug in the sockets, providing…

Lasting devastation from Tonga volcano eruption revealed in satellite images

Tonga’s volcanic eruption has left behind damage so severe that satellites can see it from space. On Saturday (Jan. 15), the volcano erupted on the island Hunga Tonga-Hunga Ha’apai in the South Pacific kingdom of Tonga after it began brewing a couple of days earlier. It was the volcano’s second explosive event in two months, and this eruption was seven times as powerful as the previous eruption in December, with its consequences reaching out thousands of miles across planet Earth.  “A volcanic mushroom plume was released reaching the stratosphere and…
