SpaceX has scrubbed the launch of NASA’s TESS exo-planet hunting satellite, which had been planned for Monday evening.
“Standing down today to conduct additional GNC analysis, and teams are now working towards a targeted launch of @NASA_TESS on Wednesday, April 18,” the company tweeted.
Meanwhile, Vice President Mike Pence addressed the 34th Space Symposium in Colorado Springs earlier today. He made the following announcements:
Ret. Adm. Jim Ellis has been named to lead the National Space Council’s Users Advisory Group; and,
The space council has come up with a set of guidelines on space traffic management that will be signed by President Donald Trump and implemented by the Commerce Department. A key goal of the new guidelines is to deal with the threat of orbital debris.
The NASA Innovative Advanced Concepts (NIAC) program recently awarded 25 grants for the development of visionary new technologies. Here we’re going to take a closer look at the following two Phase II awards focused on space astronomy.

Each award is worth up to $500,000 for a two-year study. Descriptions of the awards are below.
GREENBELT, Md. (NASA PR) — NASA’s Transiting Exoplanet Survey Satellite (TESS) is undergoing final preparations in Florida for its April 16 launch to find undiscovered worlds around nearby stars, providing targets where future studies will assess their capacity to harbor life.
Despite a last minute threat of a veto, President Donald Trump signed an $1.3 trillion omnibus spending bill on Friday that boosts NASA spending by about $1.1 billion to $20.7 billion.
So, with the fiscal year nearly half over, let’s take a closer look at NASA’s FY 2018 budget, which the Administration had tried to cut. The table below lays out the numbers from the omnibus bill, the Administration’s request and the FY 2017 budget.
SWINDON, England (UKSA PR) — A multi-million pound European mission to study newly discovered planets will be led by University College London, supported by investment from the UK Space Agency.
The ARIEL (Atmospheric Remote-sensing Infrared Exoplanet Large-survey) mission was selected today as the next European Space Agency (ESA) science mission, putting UK leadership at the heart of research into planets that lie outside our solar system – exoplanets.
Thousands of exoplanets have now been discovered with a huge diversity of masses, sizes and orbits, but very little is known about their chemical composition, formation, or their evolutionary links to their host stars.
WASHINGTON, DC (NASA PR) — Join NASA at 1 p.m. EDT Wednesday, March 28, as astrophysics experts discuss the upcoming launch of NASA’s next planet hunter, the Transiting Exoplanet Survey Satellite (TESS). Reporters can attend the event in person at the James Webb Auditorium at NASA Headquarters in Washington or participate by phone.
The briefing will be broadcast live on NASA Television and the agency’s website.
MOFFETT FIELD, Calif. (NASA PR) — Trailing Earth’s orbit at 94 million miles away, the Kepler space telescope has survived many potential knock-outs during its nine years in flight, from mechanical failures to being blasted by cosmic rays. At this rate, the hardy spacecraft may reach its finish line in a manner we will consider a wonderful success. With nary a gas station to be found in deep space, the spacecraft is going to run out of fuel. We expect to reach that moment within several months.

Kennedy Space Center Director Bob Cabana recently spoke to spaceport employees about plans for 2018. The coming year will be highlighted by NASA’s Commercial Crew Program (CCP) partners preparing to launch test flights for crewed missions to the International Space Station.
“This is going to be an awesome year for us,” Cabana said speaking to center employees on Jan. 11, in the Lunar Theater of the Kennedy Space Center Visitor Complex’s Apollo Saturn V Center. “The number one priority this year is we’ve got to get commercial crew flying to the International Space Station.”
I realize it’s a bit late, but here’s a look back at the major developments in space in 2017.
I know that I’m probably forgetting something, or several somethings or someones. Fortunately, I have eagle-eyed readers who really seem to enjoy telling me just how much I’ve screwed up. Some of them a little too much….
So, have at it! Do your worst, eagle-eyed readers!
An international fleet of spacecraft will be launched in 2018 to explore the Moon, Mars, Mercury and the Sun. Two sample-return spacecraft will enter orbit around asteroids while a third spacecraft will be launched to search for asteroids that contain water that can be mined.
NASA will also launch its next exoplanet hunting spacecraft in March. And the space agency will ring in 2019 with the first ever flyby of a Kuiper Belt object.
And, oh yes, Elon Musk is launching his car in the direction of Mars. (more…)
Direct Multipixel Imaging and Spectroscopy of an Exoplanet with a Solar Gravity Lens Mission

We propose to study a mission to the deep regions outside the solar system that will exploit the remarkable optical properties of the Solar Gravitational Lens (SGL) focus to effectively build an astronomical telescope capable of direct megapixel high-resolution imaging and spectroscopy of a potentially habitable exoplanet. Although theoretically it seems feasible, the engineering aspects of building such an astronomical telescope on the large scales involved were not addressed before; we propose to do that.
Our main question for this study is not “how to get there?” (although it will also be addressed), but rather “what does it take to operate a spacecraft at such enormous distances with the needed precision?”
Specifically, we propose to study I) how a space mission to the focal region of the SGL may be used to obtain high-resolution direct imaging and spectroscopy of an exoplanet by detecting, tracking, and studying the Einstein’s ring around the Sun, and II) how such information could be used to unambiguously detect and study life on another planet.
All stars exhibit intensity fluctuations over several time scales, from nanoseconds to days; these intensity fluctuations echo off planetary bodies in the star system and provide an opportunity to detect and possibly image exoplanets using modern computational imaging techniques.
A mission utilizing stellar echo detectors could provide continent-level imaging of exoplanets more readily than interferometric techniques, as high temporal resolution detection is less technically challenging and more cost effective than multikilometer-baseline fringe-tracking, particularly in a photon-starved regime.
The concept is also viable for survey missions for detecting exoplanets at more diverse orbital inclinations than is possible with transit or radial velocity techniques.
Under a Phase I NIAC program, we evaluated the feasibility of the stellar echo technique and, while several practical constraints have been identified, we have not identified any fundamental limitations.
We determined that the foundational technology already exists and has high TRL in space missions. Furthermore, the measurements required to demonstrate the feasibility of stellar echo detection are complementary to asteroseismology measurements, so a demonstration mission would provide high-value scientific information to other active astrophysics programs.
Under the Phase II program, we will continue to advance the theoretical understanding of stellar echo imaging, improve on the computational methods developed in Phase I, evaluate specific hardware implementations, and ultimately produce a roadmap for the demonstration of stellar echo detection and imaging of exoplanets.
Video Caption: Seven Earth-sized planets have been observed by NASA’s Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone.
Over 21 days, NASA’s Spitzer Space Telescope measured the drop in light as each planet passed in front of the star. Spitzer was able to identify a total of seven rocky worlds, including three in the habitable zone, where liquid water might be found.
The video features interviews with Sean Carey, manager of the Spitzer Science Center, Caltech/IPAC; Nikole Lewis, James Webb Space Telescope project scientist, Space Telescope Science Institute; and Michaël Gillon, principal investigator, TRAPPIST, University of Liege, Belgium.
The system has been revealed through observations from NASA’s Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope.
