-There isn’t enough evidence yet to declare a groundbreaking discovery that definitively says dark energy is evolving and weakening, but that could change within just a couple of years, Ishak-Boushak said.
+It’s the first time Starship, a vehicle intended to eventually carry humans to the moon and Mars, has successfully ignited one of its Raptor engines while in space, according to SpaceX.
-“My first big question is if we will continue to see evidence for evolving dark energy as our measurements get better and better,” Martini said. “If we do get to the point where the evidence is overwhelming, then my next questions will be: How does dark energy evolve? And what are the most likely physical explanations?”
+That’s a big deal, explained Garret Reisman, a former NASA astronaut who now advises for SpaceX.
-The new data release could also help astrophysicists better understand how galaxies and black holes evolve and the nature of dark matter. Although dark matter has never been detected, it is believed to make up 85% of the total matter in the universe.
+“They’re finicky little beasts — (the Starship rocket engines) — and it’s not so easy to light them up and shut them down and light them up again,” Reisman told CNN.
-Scientists involved with the collaboration are eager to improve their measurements using DESI.
+Starship then aimed to test its limits as it headed toward splashdown in the Indian Ocean.
-“Whatever the nature of dark energy is, it will shape the future of our universe,” said Michael Levi, DESI director and a scientist at the Lawrence Berkeley National Laboratory. “It’s pretty remarkable that we can look up at the sky with our telescopes and try to answer one of the biggest questions that humanity has ever asked.”
+“We’re going to fly the ship at an aggressive angle of attack once it’s moving slower than the speed of sound,” SpaceX engineer Jessie Anderson said on the company’s livestream. “This means we’ll be flying nose down instead of our usual belly flop orientation during final descent. This will — no doubt — stress the limits of the flaps’ ability to maintain control, but it will be a chance to get real flight data on what our limits actually are.”
+The “flaps” are small wings attached to the side of the Starship vehicle meant to brace the winds of reentry and help slow the vehicle down.
-A new experiment called Spec-S5, or Stage 5 Spectroscopic Experiment, could measure more than 10 times as many galaxies as DESI to study both dark energy and dark matter, Martini said.
+The company had also removed some protective shielding off the vehicle to see whether the Starship could survive without it.
+Starship made a safe landing in the Indian Ocean and remained intact despite the rough landing trajectory.
+“Turns out the vehicle had more capability than our calculations predicted, and that is why we test like we fly,” SpaceX engineer Kate Tice said on the livestream for the event.
