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.

This is the Hyades Cluster! ✨✨✨

As the closest star cluster to Earth, this star cluster contains hundreds of stars with some of the brighter ones in this image transforming into giant stars as they enter a new phase of their lifespan. Some theorize that the creation of this cluster may have happened all at once as many of these stars are the same age and move in a similar way! 💫💫💫

The Great Conjunction of Jupiter and Saturn

Have you noticed two bright objects in the sky getting closer together with each passing night? It’s Jupiter and Saturn doing a planetary dance that will result in the Great Conjunction on Dec. 21. On that day, Jupiter and Saturn will be right next to each other in the sky – the closest they have appeared in nearly 400 years!

Skywatching Tips from NASA

For those who would like to see this phenomenon for themselves, here’s what to do:

Find a spot with an unobstructed view of the sky, such as a field or park. Jupiter and Saturn are bright, so they can be seen even from most cities.

An hour after sunset, look to the southwestern sky. Jupiter will look like a bright star and be easily visible. Saturn will be slightly fainter and will appear slightly above and to the left of Jupiter until December 21, when Jupiter will overtake it and they will reverse positions in the sky.

The planets can be seen with the unaided eye, but if you have binoculars or a small telescope, you may be able to see Jupiter’s four large moons orbiting the giant planet.

How to Photograph the Conjunction

Saturn and Jupiter are easy to see without special equipment, and can be photographed easily on DSLR cameras and many cell phone cameras. Here are a few tips and tricks:

These planets are visible in the early evening, and you’ll have about 1-2 hours from when they are visible, to when they set. A photo from the same location can look completely different just an hour later!

Using a tripod will help you hold your camera steady while taking longer exposures. If you don’t have a tripod, brace your camera against something – a tree, a fence, or a car can all serve as a tripod for a several-second exposure.

The crescent Moon will pass near Jupiter and Saturn a few days before the conjunction. Take advantage of it in your composition!

Focus stacking o apilamiento de imágenes.

Esta técnica consiste en realizar varias fotos enfocando a un mismo objeto, sin mover la cámara, pero sí cambiando la distancia de enfoque para aumentar la profundidad de campo y conseguir que esté en foco todo lo que queramos, ya que el resultado final es la unión de todas esas imágenes.

APOD: El anillo lácteo (2021 de enero de 22)

https://apod.nasa.gov/apod/ap2 10122.htmI

Una expansión de polvo cósmico, estrellas y nebulosas a lo largo del avión de nuestra galaxia Vía Láctea forman un hermoso anillo en esta vista proyectada del cielo. El panorama creativo cubre toda la galaxia visible desde el planeta Tierra, un ambicioso mosaico de 360 grados que llevó dos años completarse.

Los sitios del hemisferio norte en el oeste de China y los lugares del hemisferio sur en Nueva Zelanda fueron utilizados para recoger los datos de la imagen. Como una joya brillante en el anillo lácteo, el bulto del centro galáctico, está en la parte superior. Planeta brillante Júpiter es el balizadorjusto encima del bulto central y izquierda de la estrella gigante roja Antares. A lo largo del avión y a casi 180 grados del centro galáctico, en el fondo del ring está la zona alrededor de Orion, denizen de los cielos de invierno del hemisferio norte. En esta proyección el anillo de la Vía Láctea abarca dos galaxias notables en los cielos del sur, las grandes y pequeñas nubes de Magallanes.
