SpaceX will launch NASA’s subsequent exoplanet mission on Sunday morning (Jan. 11), and you may watch the motion reside.
A Falcon 9 rocket carrying about 40 payloads, together with NASA’s Pandora exoplanet satellite tv for pc, is scheduled to carry off from California’s Vandenberg Area Pressure Base throughout a 57-minute window that opens at 8:19 a.m. EST (1319 GMT and 5:19 a.m. native California time).
Throughout its yearlong orbital mission, the 716-pound (325 kilograms) Pandora will examine a minimum of 20 recognized exoplanets utilizing a 17-inch-wide (45 centimeters) telescope, which it should practice on the worlds as they “transit,” or cross the face of, their host stars from the satellite tv for pc’s perspective.
Such transits trigger a small dip within the host star’s brightness, which exoplanet hunters have used to nice benefit: Many of the greater than 6,000 alien planets we all know of have been found by way of the “transit technique.”
Transits additionally permit astronomers to characterize recognized exoplanets, particularly their atmospheres. Completely different parts and molecules soak up mild at particular wavelengths, so finding out the spectrum of starlight that has handed by way of an environment can reveal an awesome deal about that environment’s composition.
Nevertheless, such work is sophisticated by stellar complexity. Star surfaces are usually not uniform; they typically characteristic patches of various brightness, just like the sunspots that speckle our personal star. Pandora will assist astronomers account for such complexity, if all goes to plan.
“Pandora goals to disentangle the star and planet spectra by monitoring the brightness of the exoplanet’s host star in seen mild whereas concurrently accumulating infrared information,” NASA officers wrote in a mission description. “Collectively, these multiwavelength observations will present constraints on the star’s spot protection to separate the star’s spectrum from the planet’s.”
Pandora will give attention to planets with atmospheres which might be dominated by water or hydrogen, company officers added.
The opposite three dozen or so satellites going up on the Twilight mission are a various group. Amongst them are 10 of Kepler Communications’ Aether spacecraft and two of Capella Area’s superior new Acadia Earth-imaging radar satellites.
SpaceX is no stranger to rideshare missions like Twilight. To date, the company has launched 15 such flights in its Transporter series and four via a different program known as Bandwagon.
Twilight will mark the fifth liftoff for this particular Falcon 9’s first stage. If all goes according to plan, the booster will land back at Vandenberg about 8.5 minutes after liftoff.
