55 Tags 0 Compartilhamentos - Space adaptation syndromeSpace adaptation syndrome (SAS) or space sickness is a condition experienced by as many as half of all space travelers during their adaptation to weightlessness once in orbit. It is the opposite of terrestrial motion sickness since it occurs when the environment and the person appear visually to be in motion relative to one another even though there is no corresponding sensation of bodily movement originating from the vestibular system. Presentation Space motion sickness can lead to degraded astronaut performance. SMS threatens operational requirements, reduces situational awareness, and threatens the safety of those exposed to micro-g environments. Lost muscle mass leads to difficulty with movement, especially when astronauts return to earth. This can pose a safety issue if the need for emergency egress were to arise. Loss of muscle power makes it extremely difficult, if not impossible, for astronauts to climb through emergency egress hatches or create unconventional exit spaces in the case of a crash upon landing. Additionally, bone resorption and inadequate hydration in space can lead to the formation of kidney...EN.WIKIPEDIA.ORG

0 Tags 0 Compartilhamentos - Final Results from the Hubble Space Telescope Key Project to Measure the Hubble ConstantWe present here the final results of the Hubble Space Telescope Key Project to measure the Hubble constant. We summarize our method, the results and the uncertainties, tabulate our revised distances, and give the implications of these results for cosmology. The analysis presented here benefits from a number of recent improvements and refinements, including (1) a larger LMC Cepheid sample to define the fiducial period-luminosity (PL) relations, (2) a more recent HST Wide Field and Planetary Camera 2 (WFPC2) photometric calibration, (3) a correction for Cepheid metallicity, and (4) a correction for incompleteness bias in the observed Cepheid PL samples. New, revised distances are given for the 18 spiral galaxies for which Cepheids have been discovered as part of the Key Project, as well as for 13 additional galaxies with published Cepheid data. The new calibration results in a Cepheid distance to NGC 4258 in better agreement with the maser distance to this galaxy. Based on these revised Cepheid distances, we find values (in km/sec/Mpc) of H0 = 71 +/- 2 (random) +/- 6 (systematic) (type Ia supernovae), 71 +/- 2 +/- 7 (Tully-Fisher relation), 70 +/- 5 +/- 6 (surface brightness fluctuations), 72 +/- 9 +/- 7 (type II supernovae), and 82 +/- 6 +/- 9 (fundamental plane). We combine these results for the different methods with 3 different weighting schemes, and find good agreement and consistency with H0 = 72 +/- 8. Finally, we compare these results with other, global methods for measuring the Hubble constant.ARXIV.ORG

7 Tags 0 Compartilhamentos - James Webb Space TelescopeThe James Webb Space Telescope (JWST) is a space telescope currently conducting infrared astronomy. As the largest optical telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. This enables investigations across many fields of astronomy and cosmology, such as observation of the first stars, the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets.The U.S. National Aeronautics and Space Administration (NASA) led JWST's design and development and partnered with two main agencies: the European Space Agency (ESA) and the Canadian Space Agency (CSA). The NASA Goddard Space Flight Center (GSFC) in Maryland managed telescope development, while the Space Telescope Science Institute in Baltimore on the Homewood Campus of Johns Hopkins University currently operates JWST. The primary contractor for the project was Northrop Grumman. The telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 during the Mercury, Gemini, and Apollo...EN.WIKIPEDIA.ORG

The James Webb Space Telescope (JWST) is a space telescope that is set to launch in 2021. It is the successor to the Hubble Space Telescope, and will be the most powerful space telescope ever built. The JWST will be able to observe objects in infrared light, allowing it to see much farther into space and time than any other telescope. It will also be able to detect planets outside of our solar system, and study the atmospheres of those planets. The JWST will help us better understand the formation and evolution of galaxies, stars, and planets, as well as provide new insights into the origin of life in our universe.By: ChatGPT AI0 Compartilhamentos -
Space adaptation syndrome (SAS) is a condition experienced by astronauts and cosmonauts during their first few days in space. It is caused by the lack of gravity and the associated sensory changes. Symptoms include nausea, vomiting, dizziness, headaches, fatigue, and disorientation. Astronauts may also experience difficulty sleeping and concentrating due to the unfamiliar environment. SAS usually resolves itself within a few days as astronauts adjust to their new environment.By: ChatGPT AI0 Compartilhamentos -
The European Space Agency (ESA) is an intergovernmental organization of 22 member states dedicated to the exploration of space. The ESA's mission is to shape the development of Europe's space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world. The ESA's activities include human and robotic spaceflight, Earth observation, science, navigation, telecommunications, exploration of Mars and the Moon, aeronautics, technology development, and operations.By: ChatGPT AI0 Compartilhamentos -
Space ice cream is a type of freeze-dried ice cream that was created to be eaten in space. It is typically sold in small packages and is made by freezing a mixture of milk, sugar, and flavorings. The mixture is then dried and compressed into a solid form. Space ice cream can be eaten without being rehydrated, making it an ideal snack for astronauts in space.By: ChatGPT AI0 Compartilhamentos -
