Finding Over 100 Million Exoplanets By 2050

Image
The cumulative number of exoplanets that have been discovered has been following power law scaling for the past 25 years and if this continued to 2050 then we would find about 100 million exoplanets.

20,000 exoplanets should be found from the past primary Kepler mission and the completed K2 mission and from the Transiting Exoplanet Survey Satellite and from the planned 2026 PLATO mission.

The Gaia mission should find between 15,000 and 90,000 depending on the final mission duration and the actual occurrence rates of massive planets in wide orbits.

The Wide-Field Infrared Survey Telescope is expected launch in 2025 and a mission duration of five years and it is supposed to find another about 70,000 to 150,000 transiting exoplanets, details depending mostly on the actual occurrence rate of hot Jupiters in the WFIRST observing fields. The total exoplanet count should be between 105,000 and 260,000 by 2030.

Elon Musk Expects Starship Flight Hopefully in Two-Three Months

Image
Space Exploration Technologies Corp. is currently building a flight design of Starship, a vehicle designed to transport people to the moon and Mars, said the rocket manufacturer’s Chief Executive Officer Elon Musk.

Starship’s first “flight is hopefully 2 to 3 months away,” Musk said in a Twitter post.

The Space Force is officially the sixth military branch. Here’s what that means.

Air Force officials on Friday told reporters that people are clamoring for information on how to join the military’s latest branch. The short answer is, they’re going to have to wait a while.

President Trump officially signed the Space Force into law Friday, but for now, all that means is everyone at Air Force Space Command will now be assigned to Space Force. Over the next 18 months, officials said, the finer details of manning and training the new branch will be hammered out and set in motion.

“It’s going to be really important that we get this right. A uniform, a patch, a song ? it gets to the culture of a service,” said Air Force Gen. Jay Raymond, the head of Air Force Space Command and U.S. Space Command, who will lead Space Force until a chief of space operations is confirmed by the Senate. “There’s a lot of work going on toward that end. It’s going to take a long time to get to that point, but that’s not something we’re going to roll out on day one.”

For now, the 16,000 active-…

Senate sends massive defense bill for Trump to sign, creating Space Force

Image
WASHINGTON - The U.S. Senate voted overwhelmingly on Tuesday to pass a $738 billion defense policy bill that creates President Donald Trump’s “Space Force” and gives federal employees 12 weeks of paid parental leave, sending it to the White House, where Trump has promised to quickly sign it into law.

The Republican-controlled Senate voted 86 to 8 in favor of the National Defense Authorization Act, or NDAA. The Democratic-led House approved the bill by 377-48 last week.

Trump said on Twitter last week that he would sign the bill as soon as it passes, saying it included all his priorities.

As one of the few pieces of major legislation Congress passes every year, the NDAA becomes a vehicle for a range of policy measures as well as setting everything from military pay levels to which ships or aircraft will be modernized, purchased or discontinued.

This year’s legislation included a 3.1% pay increase for the troops; the first ever paid family leave for all federal workers, and the creatio…

Water found an inch beneath the Martian surface could help future astronauts

Image
When the first astronauts land on Mars, they won't be able to take everything they need with them. The logistics and weight of transporting so much material on one spacecraft, along with a crew, defies current technology. While scientists at NASA have discussed missions to deliver materials to the Red Planet ahead of a manned mission, there may be resources on Mars that can be used.

One of those key resources is water, but access to the water is just as crucial to determine. Knowing the location of accessible water on Mars could even help determine a landing site for a manned mission.

A new study published this week in the journal Geophysical Research Letters shows a map of water ice that could be just an inch beneath the dusty surface.

Ahead of any manned mission, robots have been scoping out Mars for years. Rovers have investigated the surface for signs of past life and evidence of water, while orbiters looping around Mars image and map the planet.

House approves defense bill authorizing Space Force, 12 weeks of paid family leave for feds

employees and authorized the creation of President Trump's sought-after "Space Force."

The measure was passed by a final vote of 377 to 48 following several weeks of negotiation between the House and Senate, The Associated Press reported.

Certain House Democrats reportedly sought a more liberal bill that would have blocked Trump from using Pentagon funds to fulfill his campaign promise of a southern border wall. Those same members also expressed concerns about the rising deficit and national debt.

Congressional Republicans compromised on parental leave and were able to gain authorization for the building of Trump's Space Force, which would consolidate existing personnel under a new branch of the Air Force. The bill also includes a 3.1 percent military pay raise and a repeal of the widow's tax on military death benefits.

House Armed Services Committee (HASC) Chairman Adam Smith, D-Wash., declared victory for Democrats and told The Associated Press that he had pro…

U.S. Space Command chief Raymond: ‘I’m really excited for the Space Force’

Image
Raymond: "Having a Space Force with a singular focus on the space domain will be hugely, hugely helpful to us." WASHINGTON — After just a few months in existence, U.S. Space Command has grown in size, influence and is about to complete a detailed game plan for how the nation’s space assets will be defended. Its commander Gen. John “Jay” Raymond believes that the establishment of a U.S. Space Force will be a big boost to U.S. SPACECOM and to the nation’s ability to protect its satellites and defeat aggressors.
“I’m really excited for the Space Force,” Raymond said Dec. 9 at the Pentagon during an interview with SpaceNews. “I think it’s going to provide another huge advantage for our nation.”
Congressional defense committee leaders on Dec. 9 unveiled details of the conference agreement for the National Defense Authorization Act for Fiscal Year 2020 that authorizes a U.S. Space Force as an independent military branch under the Department of the Air Force.

White House, Democrats strike tentative deal to create Space Force in exchange for federal parental leave benefits: report

Image
The White House and House Democrats have reportedly reached a tentative deal to authorize the creation of the Space Force, a priority for the Trump administration first outlined in an executive order by the president earlier this year.

The Washington Post reported Sunday that Democrats and White House negotiators had struck a bargain that would authorize the creation of the agency in exchange for a policy establishing 12 weeks of paid parental leave for federal workers.

It isn't clear if the plan will be able to win enough Republican support to pass the Senate, according to the Post, but the plan appears to have the backing of both President Trump and Speaker Nancy Pelosi (D-Calif.), a rare moment of compromise amid the House's impeachment hearings.

“Trump doesn’t like the so-called ‘deep state’ and I doubt that he’s going to bed at night saying, ‘Look what I did for federal workers,’” Rep. Don Beyer (D-Va.) told the Post. “But it was a trade-off for him. And it’s good policy…
