SPACE EXPLORATION WHAT S NEXT FOR NASA

What's Next For NASA?

NASA's vision: We reach for new heights and reveal the unknown for the benefit of humankind.
Thousands of people have been working around the world -- and off of it -- for decades, trying to answer some basic questions. What's out there? How do we get there? What will we find? What can we learn there, or learn just by trying to get there, that will make life better here on Earth?
Explore our history, see who we are and how we work, check the list of current missions, and find out what we're launching next.  Here’s a look at some of the big things coming up.
This is NASA's 2018 'To Do' list. The work we do, which will continue in 2018, helps the United States maintain its world leadership in space exploration and scientific discovery. Launches, discoveries and more exploration await in the year ahead.

NASA will add to its existing robotic fleet at the Red Planet with the InSight Mars lander set to study the planet’s interior.  The Mars 2020 rover will look for signs of past microbial life, gather samples for future return to Earth and investigate resources that could someday support astronauts.
The James Webb Space Telescope will be the premier observatory of the next decade, studying every phase in the history of our Universe in infrared, while the Parker Solar Probe will “touch the sun,” travelling closer to the surface than any spacecraft before.
NASA’s first asteroid sample return mission, OSIRIS-REx, arrives at the near-Earth asteroid Bennu in August 2018, and will return a sample for study in 2023.
Launching no later than June 2018, the Transiting Exoplanet Survey Satellite (TESS) will search for planets outside our solar system by monitoring 200,000 bright, nearby stars.
And a mission to Jupiter's ocean-bearing moon Europa is being planned for launch in the 2020s.

Building on this growing scientific knowledge of our solar system, NASA is developing the most advanced rocket and spacecraft to lead the next steps of human exploration farther into space than we have ever traveled before. Launching from a revitalized NASA Kennedy Space Center in Florida, the agency’s powerful Space Launch Systemrocket will carry astronauts aboard NASA's Orion spacecraft to the Moon, where astronauts will build and begin testing the systems needed for challenging missions to other destinations, including Mars, and deeper into space.  
 
NASA will test its new deep space exploration system beginning with an integrated, uncrewed flight of SLS and Orion, known as Exploration Mission-1. During the second and subsequent early flights, NASA will develop new technologies and techniques and apply innovative approaches to solving problems in preparation for longer-duration missions far from Earth. NASA will build up its deep space capabilities before ultimately sending humans to the Red Planet.

Humans are already living and working off the Earth in the one-of-a kind research laboratory in microgravity. The International Space Station serves as a blueprint for global cooperation and scientific advancements, a destination for growing a commercial marketplace in low-Earth orbit, and a test bed for demonstrating new technologies. Research on the station is the springboard to NASA’s next great leap in exploration, sending humans into deep space.
A new generation of U.S. commercial spacecraft and rockets are supplying cargo to the space station and will soon launch astronauts once again from U.S. soil.
By studying astronauts living in space for six months or more -- including two who were there for nearly a year -- NASA is learning how future crews can thrive on longer missions farther into the solar system. The space station also is a test bed for exploration technologies like autonomous refueling of spacecraft, advanced life support systems and human/robotic interfaces.
A portion of the astronauts’ time aboard the space station has been designated for national laboratory investigations that provide direct benefits to improve life on Earth, and NASA is committed to using this unique resource for wide-ranging scientific research.

WHERE ARE DREAMERS NOW ?

THE WASHINGTON POST 


Up next in the Senate: Immigration. And nobody knows what will happen.

A long-anticipated showdown on immigration reform is coming this week — and nobody knows how it will turn out.
The Senate is set to begin debate Monday night on an issue that has vexed lawmakers for years, probably signaling whether the closely divided chamber has any hope of striking a bipartisan compromise.
Among other challenges is whether Congress can find a way to protect “dreamers” — as a majority of Americans want for those young undocumented immigrants brought to the United States as children — while also enacting changes in border security eagerly sought by President Trump.
“We’re going to have something in the Senate that we haven’t had in a while,” Sen. Jeff Flake (R-Ariz.) said Sunday on NBC’s “Meet the Press.” “It’s a real debate on an issue where we really don’t know what the outcome is going to be.”
And few are saying much publicly about what they’re planning.
“I’m not trying to tilt the playing field in any particular direction,” Senate Majority Leader Mitch McConnell (R-Ky.) said last week about the forthcoming immigration debate. (Melina Mara/The Washington Post)
“There’s not a lot of deep planning that’s gone on,” said Frank Sharry, founder and executive director of America’s Voice, an immigration advocacy organization. “Everyone was focused on what was going on with the shutdown. I think it is going to have a helter-skelter quality to it.”
Even if the Senate is able to pass a bill, it’s far from certain that the House will move ahead with it. Speaker Paul D. Ryan (R-Wis.) said last week that the House “will bring a solution to the floor, one the president will sign.”
What exactly Trump will support remains crucial yet unknown, as he has shown little willingness to accept anything short of the four-part plan he proposed last month.
In a weekend tweet, he reiterated support for “creating a safe, modern and lawful immigration system” that includes more border security, ending family-based legal migration and ending the diversity lottery program. He made no mention of his support for protecting 1.8 million dreamers, whose status was thrown into uncertainty when he canceled an Obama-era program known as Deferred Action for Childhood Arrivals, or DACA.
“It’s time for Congress to act and to protect Americans,” Trump said in a video message released late Saturday. “Every member of Congress should choose the side of law enforcement and the side of the American people. That’s the way it has to be.”

Trump sparked the debate in September by announcing the end of DACA, which grants temporary legal status to roughly 690,000 dreamers. He has given lawmakers until March 5 to enact a permanent solution.
But Congress has failed for years to secure the votes to pass a Dream Act, as the legislation has become known.
Supporters of such legislation had hoped to tie it to the debate over spending, which has prompted two short-lived government shutdowns in recent weeks. Although that didn’t happen, Senate Majority Leader Mitch McConnell (R-Ky.) did agree to set the immigration debate in motion last month when, facing pressure from senators in both parties, he said he would permit up-or-down votes on immigration proposals in exchange for ending the first shutdown, last month, which lasted three days.
“I’m not trying to tilt the playing field in any particular direction,” he said last week when asked about the debate.
Unlike most congressional debates, which begin with a prepared piece of legislation, the give-and-take over immigration will not. Instead, McConnell used his powers as floor leader late last week to bring up an unrelated bill that he said will be used as the “shell” for the debate. The shell can be reshaped when a proposed amendment has the 60 votes needed to clear procedural challenges and pass. Once amendments are added, the final bill will also require at least 60 votes to survive and pass.
“Every ounce of energy this week is going to be spent on crafting a bill that protects dreamers and can get 60 votes,” Senate Minority Leader Charles E. Schumer (D-N.Y.) said in a statement. “It’s a hard needle to thread, but we are making progress.”
Flake said in a separate interview last week that immigration “is something that Mitch has been loathe to address; we know that.” The forthcoming debate “may not yield anything — that’s dangerous in and of itself — but we just don’t know what coalitions will develop and what amendments will gain steam.”
Liberal organizations and immigration reform advocates are warily watching the debate, pushing for a narrow fix to protect dreamers and warning that they will hold Democrats and vulnerable Republicans accountable if they cannot keep Trump’s proposed policy changes to a minimum.
“Our nightmare scenario is that we get into a long-term conversation about immigration,” said Angel Padilla, policy director for Indivisible, a grass-roots liberal organization. “There are things that need to be addressed for sure that should be addressed separately, but that will only block actual real solutions for dreamers.”
Aides in both parties and advocates tracking the debate expect that Democrats and Republicans will try introducing proposals to test the Senate’s appetite for reform.
Sen. Susan Collins (R-Maine) has been hosting meetings in her office since last month’s shutdown, trying to get about 25 senators in a bipartisan “Common Sense Caucus” to endorse a plan that could pass overwhelmingly. After several long meetings fueled by several boxes of Girl Scout cookies, they still have nothing.
“I don’t know whether we can get there or not,” she said.
Sen. Amy Klobuchar (D-Minn.), a member of the group, said the talks are “a true test for the U.S. Senate: Will senators go to the opposite corners of the partisan boxing ring, or will they come together to resolve a critical issue?”
A bipartisan proposal by Sens. John McCain (R-Ariz.) and Christopher A. Coons (D-Del.) has already been dismissed by Trump as a “waste of time.” It would grant legal status to a larger pool of undocumented immigrants than the 1.8 million Trump supports legalizing and not immediately authorize spending the $25 billion Trump wants to fortify the southern border. Their bill also says nothing about curbing family-based legal migration or making changes to the diversity lottery program.
Democrats, meanwhile, are expected to introduce a new version of the Dream Act, a bill first introduced during George W. Bush’s presidency that would provide a pathway to citizenship for millions of dreamers. A majority of Americans support the concept, but it is opposed by most Republicans unless it is passed alongside changes in border security.
Sen. Richard J. Durbin (D-Ill.), the lead Democratic negotiator on immigration, is the longtime lead sponsor of the Dream Act. If he doesn't introduce it, Democratic Sens. Kamala D. Harris (Calif.), Cory Booker (N.J.) or Kirsten Gillibrand (N.Y.), or Sen. Bernie Sanders (I-Vt.) — all of whom are mulling 2020 presidential bids — might assume the mantle.
Divisions among Republican senators have flared up in recent weeks over what should be an in immigration bill, adding to the complications of securing an agreement.
Sen. John Thune (R-S.D.) said at a GOP congressional retreat this month that a narrow measure addressing the fate of young immigrants and border security may be the best deal the Senate can pass. But Sen. James Lankford (R-Okla.) has said he has no interest in what he termed a “skinny” immigration framework.
“Everybody's trying to figure out the chaos of next week. So I don't know yet how open the process is going to be,” Lankford said.
Seen as a bridge between conservatives in his party and the bipartisan group, Lankford is pushing an idea to grant dreamers five years of “conditional permanent residency” so long as they remain employed, in school or serving in the military. If they maintained that status for 10 years, they could then seek a green card. And five years after that, they could apply for citizenship.
Sens. John Cornyn (R-Tex.), Charles E. Grassley (R-Iowa) and Thom Tillis (R-N.C.) have also introduced plans to fortify the U.S.-Mexico border and may take the lead in introducing Trump’s four-part immigration plan as a separate piece of legislation, according to aides familiar with the ongoing talks.
Two of Trump’s staunchest allies, Sens. David Perdue (R-Ga.) and Tom Cotton (R-Ark.), back his immigration plan but also want to curb legal immigration — an idea long championed by White House domestic policy aide Stephen Miller but opposed by other GOP lawmakers.
