Blue Origin Completó Con éxito La Decimotercera Misión New Shepard El 13 De Octubre De 2020. New Shepard

¿Han identificado constelaciones antes?

El autor nos comenta que para esta foto tuvo que esperar que la lluvia de meteoros de las Perseidas se terminara. En ella se pueden identificar algunas de las constelaciones que logramos ver a primeras horas de la noche durante el invierno. El grupo de estrellas que más podemos visualizar es el grupo de las Pléyades en la esquina superior derecha.

Rocket Launches and Rising Seas

At NASA, we’re not immune to effects of climate change. The seas are rising at NASA coastal centers – the direct result of warming global temperatures caused by human activity. Several of our centers and facilities were built near the coast, where there aren’t as many neighbors, as a safety precaution. But now the tides have turned and as sea levels rise, these facilities are at greater risk of flooding and storms.

Global sea level is increasing every year by 3.3 millimeters, or just over an eighth of an inch, and the rate of rise is speeding up over time. The centers within range of rising waters are taking various approaches to protect against future damage.

Kennedy Space Center in Florida is the home of historic launchpad 39A, where Apollo astronauts first lifted off for their journey to the Moon. The launchpad is expected to flood periodically from now on.

Like Kennedy, Wallops Flight Facility on Wallops Island, Virginia has its launchpads and buildings within a few hundred feet of the Atlantic Ocean. Both locations have resorted to replenishing the beaches with sand as a natural barrier to the sea.

Native vegetation is planted to help hold the sand in place, but it needs to be replenished every few years.

At the Langley Research Center in Hampton, Virginia, instead of building up the ground, we’re hardening buildings and moving operations to less flood-prone elevations. The center is bounded by two rivers and the Chesapeake Bay.

The effects of sea level rise extend far beyond flooding during high tides. Higher seas can drive larger and more intense storm surges – the waves of water brought by tropical storms.

In 2017, Hurricane Harvey brought flooding to the astronaut training facility at Johnson Space Center in Houston, Texas. Now we have installed flood resistant doors, increased water intake systems, and raised guard shacks to prevent interruptions to operations, which include astronaut training and mission control.

Our only facility that sits below sea level already is Michoud Assembly Facility in New Orleans. Onsite pumping systems protected the 43-acre building, which has housed Saturn rockets and the Space Launch System, from Hurricane Katrina. Since then, we’ve reinforced the pumping system so it can now handle double the water capacity.

Ames Research Center in Silicon Valley is going one step farther and gradually relocating farther south and to several feet higher in elevation to avoid the rising waters of the San Francisco Bay.

Understanding how fast and where seas will rise is crucial to adapting our lives to our changing planet.

We have a long-standing history of tracking sea level rise, through satellites like the TOPEX-Poseidon and the Jason series, working alongside partner agencies from the United States and other countries.

We just launched the Sentinel-6 Michael Freilich satellite—a U.S.-European partnership—which will use electromagnetic signals bouncing off Earth’s surface to make some of the most accurate measurements of sea levels to date.

Roman’s Heat-Vision Eyes Are Complete!

Our Nancy Grace Roman Space Telescope team recently flight-certified all 24 of the detectors the mission needs. When Roman launches in the mid-2020s, the detectors will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of huge patches of the sky. These images will help astronomers explore all kinds of things, from rogue planets and black holes to dark matter and dark energy.

Eighteen of the detectors will be used in Roman’s camera, while another six will be reserved as backups. Each detector has 16 million tiny pixels, so Roman’s images will be super sharp, like Hubble’s.

The image above shows one of Roman’s detectors compared to an entire cell phone camera, which looks tiny by comparison. The best modern cell phone cameras can provide around 12-megapixel images. Since Roman will have 18 detectors that have 16 million pixels each, the mission will capture 300-megapixel panoramas of space.

The combination of such crisp resolution and Roman’s huge view has never been possible on a space-based telescope before and will make the Nancy Grace Roman Space Telescope a powerful tool in the future.

This is Herschel’s Garnet Star! 🌟🌟🌟

If Herschel’s Garnet Star and the Sun were placed both at a same distance of 10 parsecs, this star would be 100,000 times brighter than our Sun! It is so big that if it were in the Solar System, it would engulf up to the orbit of Jupiter! ✨✨✨
