Astronomers want to get in on NASA’s push to the moon
In that timeline, JWST would have launched in October and completed its six-month commissioning phase in the spring of —time for astronomers to start using the telescope and presenting the results, from observations of the solar system to distant galaxies, at one of the biggest astronomy conferences of the year. Instead, in this reality JWST remains in a clean room at a Northrop Grumman facility in Southern California, still undergoing tests ahead of a launch now scheduled for late March At a JWST town hall at the conference, program officials emphasized that work on the telescope was now going well after a series of programs delayed its launch by two and a half years. Last spring, Tom Young, the retired aerospace executive who chaired the independent review board that studied JWST, warned that schedule reserves appeared to be consumed at a higher-than-expected rate, suggesting that they would be used up and force a delay in the launch to compensate. Project officials said last fall that they were down to two months of schedule reserves, the same figure Smith quoted at the town hall meeting. However, project leaders at both NASA and Northrop Grumman, the JWST prime contractor, said in interviews during the AAS conference that they were optimistic that, despite that limited schedule reserve, the mission could remain on track for launch next March, based on the progress the project has made and the work ahead of it.

You used to need charts, maps, and telescopes to gaze at the night sky and understand what you were looking at. Backyard stargazers use apps to discover a wealth of information on the location and identity of planets , stars, and galaxies — no telescope needed. The best astronomy apps use the gyroscope and compass in your smartphone or tablet, along with date, time, and location services, to determine your whereabouts.
Because the Earth rotates every 24 hours and the planets orbit around the sun every Your location dictates which constellations are visible. The Messier List , for example — researched and published by Charles Messier in — includes deep-sky objects viewable from the Northern Hemisphere and is a popular feature for such apps. Here are a few of the many cross-platform iOS and Android apps we discovered.
Just hold up your phone, use a pinch-to-zoom gesture, and have the app pinpoint whatever is up there. After determining your position, the app locates stars, the moon, planets, and constellations.

SpaceX now dominates rocket flight, bringing big benefits—and risks—to NASA
The giant impact hypothesis is consistent with our ideas for how planets were assembled and explains some important features of the Earth-Moon system, such as why the Moon has only a tiny metallic core. Angular momentum is the measure of motion of objects in curved paths, including both rotation and orbital motion.

In , ESA selected ‘The Gravitational Universe’ as the theme for its third Large-class mission L3 in ESA’s “Cosmic Vision ” program in which it committed to launch a space-based gravitational wave observatory in the early s.
LISA will consist of three spacecraft flying 5 million kilometers km apart in the shape of an equilateral triangle. The center of the triangle formation will be in the ecliptic plane 1 AU million km from the Sun and 20 degrees behind the Earth. The main objective of the LISA mission is to observe gravitational waves from galactic and extra-galactic binary systems , including gravitational waves generated in the vicinity of the very massive black holes found in the centers of many galaxies.
Gravitational waves are one of the fundamental building blocks of our theoretical picture of the universe. The three LISA spacecraft flying in formation will act as a giant Michelson interferometer, measuring the distortion of space caused by passing gravitational waves. Each spacecraft will contain two free-floating ‘proof masses’.
The proof masses will define optical paths 5 million km long, with a 60 degree angle between them. This mission is an X-ray observatory which will be designed to address key questions in astrophysics, including: “How and why does ordinary matter assemble into the galaxies and galactic clusters that we see today?
It now seems that the March launch date will be delayed. Astronomers have to get their proposals for “telescope time” in to observatories After launch on an Ariane 5 rocket—the European Space Agency’s (ESA).
HST provides high-resolution data that is used to understand the structure within galaxies and differentiate the light originating from stars from that originating from black holes. It also has the sensitivity to see the faintest and most distant galaxies. Spitzer is a 85cm diameter telescope operating at Infrared and Mid-infrared wavelengths. Spitzer allows scientists to peer into cosmic regions that are hidden from optical telescopes, including dusty stellar nurseries and the centers of galaxies as well as seeing starlight from very distant galaxies at the edge of the universe.
Herschel is a 3. Operated by the European Space Agency, Herschel is the largest, infrared telescope ever flown in space. Herschel data allows scientists to probe the origin and evolution of stars and galaxies to help understand how the Universe came to be the way it is today. Additionally, GALEX observations are investigating the causes of star formation during a period when most of the stars and elements we see today had their origins.
It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. These data allow astronomers to find black holes and see the hot gas in clusters of galaxies.
Chandra is designed to observe high resolution X-rays images from high-energy regions of the universe. The Jansky Very Large Array, one of the world’s premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration on the Plains of San Agustin fifty miles west of Socorro, New Mexico. Each antenna is 25 meters 82 feet in diameter.

The occasion marks yet another milestone for the private California company, which over the past decade has gone from underdog to dominator. It has lowered the cost of spaceflight through innovations such as reusable stages and fairings, saving NASA money. With its outsize capacity, Starship could cheaply put large telescopes in orbit and heavy science experiments on moons and planets. Yet SpaceX, with a fast-and-loose Silicon Valley mindset, has overlooked the potential for its technologies to contaminate night skies and pristine planets.
Between and , the first three flights of its Falcon 1 rocket ended in failure. Since then, its ambitions have grown. It turns out that having a goal can be economically successful. Cheaper, more frequent flights could improve the biomedical and physical science experiments aboard the station, says industry analyst Laura Forczyk, owner of the space consulting firm Astralytical. In , it is set to launch the Psyche mission to a metallic asteroid, in the first NASA launch of a Falcon Heavy, which sits between the Falcon 9 and Starship in its propulsive power.
Balancing astronomical visions with budgetary realities
Received: 6 December Accepted: 6 April The concept EHI design consists of two or three satellites in polar or equatorial circular medium-Earth orbits MEOs with slightly different radii. On long baselines, where the signal-to-noise ratio may be low, fringes could be detected assuming that the system is sufficiently phase stable and the satellite orbits can be reconstructed with sufficient accuracy. Averaging visibilities accumulated over multiple epochs of observations could then help improving the image quality.
With three satellites instead of two, closure phases could be used for imaging.

Astronomers hope IXPE will reveal the spin of black holes, and yield new discoveries about the extreme magnetic fields around a special type of neutron star called magnetars. In order to obtain the sensitivity required for the X-ray research, the IXPE observatory will host three identical X-ray telescopes that will be extended after launch on a foot 4-meter boom. The team at Marshall will assemble, calibrate and test the mirrors before shipping the flight units to Ball Aerospace for integration on the spacecraft, Hertz said.
So not only was it a schedule hit, it was also a budget hit. According to Porter, IXPE is currently predicted to weigh around pounds kilograms at launch, and will deploy off the Falcon 9 rocket into an unusual mile-high kilometer equatorial orbit with an inclination of 0. GUSTO, a high-altitude balloon-borne infrared telescope to study the interstellar medium, remains on track for launch from Antarctica in December Hertz said two major subcontractors working on the SPHEREx mission could not start work on schedule due to the coronavirus pandemic.
Teams worked at about 40 percent efficiency for several months, but starting staffing at higher levels in June to prepare for a series of key ground tests later this year. August 20, Breaking News. Twitter Facebook.

After weeks of downtime in the wake of the coronavirus, engineers have resumed near-normal work readying the James Webb Space Telescope for launch. NASA science chief Thomas Zurbuchen said earlier this week that launch, which had been targeted for next March, will be delayed to later in the year. The deployable tower assembly , or DTA, is a critical component that will enable the telescope to operate at the ultra-low temperatures required for its planned infrared observations of the early universe.
Resembling a large black pipe, the DTA is made out of graphite-epoxy composite material, stretching 3 metres 10 feet when full extended. This was the first time that this part of Webb was tested in its flight-like configuration to the highest level of fidelity we possibly could.
