Space is an incredible subject to study, and it wouldn’t be possible without the collection of Moon rocks and dust, as well as information about the Universe scientists have gathered.In building 31 north at the Johnson Space Center, NASA’s Lunar Lab houses some of the most famous rocks from all the Apollo missions. They have over 100,000 rocks from space.Charis Krysher, a Lunar Curation Processor for NASA, says moon rocks and space dust are the most important thing brought back to Earth.“One of the first things that we learned from the Apollo collection was how old the moon the Earth was,” Krysher says.Rocks on Earth aren’t pristine like they are on the Moon. Moon rocks don’t age, because there is no atmosphere in space to break down the rocks. The rocks found on the moon can potentially be billions of years old. “More recently we've actually learned in the past, less than a decade, that the Moon's rocks actually contain way more water than was originally realized,” the processor explains. Just like famous diamonds and jewels, there are well known space rocks, too. Like the one found by Apollo 15. “They named it the Genesis Rock, because it’s a part of the primordial crust of the moon,” she says.When studying these samples, scientists take all the precautions, from wearing bunny suits, temperature-controlled rooms and even triple bagging each rock for storing."We try really hard to preserve the rocks so that the science that we learn from the rocks can be trusted," Krysher says.It’s not every day we go to the Moon, so these scientists take time to study the rocks and do it sparingly. They are still breaking rocks over 40 years old. However, come five years from now, they’ll get another chance for more rocks when U.S. astronauts head to the moon in 2024. 1796

She has had to defend her actions multiple times in the past 24 hours as conservative critics around the nation pick on freshman Congresswoman Alexandria Ocasio-Cortez (D-NY).First, she was booed when she offered her vote to elect Nancy Pelosi as the Speaker of the House on Thursday. Of the 200 Dems who voted for Pelosi, she was the only one who received so many boos.Next, an anonymous Twitter account posted video of Ocasio-Cortez dancing in college. That gesture backfired: The response was more support for her. The Twitter handle was mysteriously deleted. 574

SEATTLE — U.S. researchers have given a healthy volunteer the first shot of an experimental coronavirus vaccine as anxiously awaited testing opens. Monday’s milestone is just the first step in a long process. The effort is one of several worldwide hunting for protection against COVID-19, even as the pandemic grows. The study is run by scientists at the Kaiser Permanente Washington Research Institute in Seattle. The shots were developed by the National Institutes of Health in record time after the new coronavirus exploded from China. Experts say it will be at least a year before any vaccine is ready for widespread use. 637

Sen. Elizabeth Warren delivered her first live pitch to presidential primary voters in Iowa on Friday night with a signature and searing indictment of the powerful interests she blames for corrupting government and decimating the American working class.The trip is an early test for the Massachusetts Democrat's growing political operation, which unveiled a slate of touted hires this week, and a candidate determined to show that her populist economic message can conjure up excitement for her campaign in Iowa's traditional proving grounds."This is the fight of our lives," Warren told an overflow crowd at an event space attached to a bowling alley in Council Bluffs, the first stop in a swing that will include at least four more over the weekend. "I am determined that we build an America where not just the children of rich people get a chance to build something, but where all of our children get a chance to build a real future. That's what I'm in this fight for."During a question and answer session that followed her remarks, Warren was quizzed on where she thought the Democratic Party was headed in the run-up the 2020 election. After touting the public education -- and government investment in the economy -- that provided her a pathway to personal and professional successes, she boiled it down to a single issue."The fundamental question, the sole question," facing the party and voters, Warren said, is "who do we want government to work for?"Warren's travels will first track the state's western border, taking her from Council Bluffs up to a Saturday event in Sioux City. Then it's a dash east to Storm Lake before setting out for Des Moines. Warren will also convene a conversation with female leaders in nearby Ankeny on Sunday morning.The trip is her first here in more than four years -- an aide confirmed that her last visit to Iowa came in October 2014 to campaign for former Rep. Bruce Braley when he ran, unsuccessfully, for Senate against Republican Joni Ernst.This time around, Warren took center stage.With the the launch of a presidential exploratory committee on Monday, she effectively kicked off the 2020 primary more than 13 months before caucusgoers in Iowa will begin casting their votes. By Friday, she was standing in front of 500 people, according to a staffer -- 300 inside, 200 outside on a crisp western Iowa night -- pitching herself, and her message, as the antidote to growing economic inequity and a faltering health care system.But she also faced at least one fraught question, from a former student who said she backed Warren's bid but worried that her former professor's support for abortion rights would sink her chances in the Midwest.Warren greeted her old friend warmly, but dug in on her position."For me, this is a question about the role of law," she said. "I know that these are very hard personal family decisions. I think the role of government here is to back out. I think a woman makes a decision with her family, her priest, her doctor, the people the woman chooses, and I think that's what respects all of us the most."Warren's remarks, which were briefly rendered almost inaudible when her mic lost power, included a call to volunteer and back a campaign she has pledged will not accept corporate cash."This is going to be a grass-roots campaign," Warren said. "I'm here to ask every one of you to be a part of this, anything you can do: Volunteer, take a sign, pitch in five bucks, any part of it."Jumping out of the gate on the last day of 2018, before so many other likely candidates but only after hundreds of post-midterm election calls to grass-roots leaders in key early voting states including New Hampshire, South Carolina and Nevada, allowed her to seize the national spotlight. Warren has since 3783
