Man Made Object In Space

           Top Man Made Object In Space

Here are some notable man-made objects in space:

1. International Space Station (ISS):

The International Space Station is bigger than a football field, measuring around 356 feet by 240 feet. The International Space Station (ISS) far surpasses Skylab and the Russian Mir in size, weighing in about 450 tons (just under 900,000 pounds). Instead of being launched all at once, the station was constructed in 2011 using pressurized modules. It has trusses for structural support and solar panels for electricity. 


2. Hubble Space Telescope:

Since 1990, the Hubble space telescope has been the biggest of its type. Hubble weighs roughly 27,000 pounds, or the equivalent of two fully grown African elephants, and measures about 43.5 feet long, or the length of a big school bus, having made more than 1.3 million observations since its launch. The aiming precision of.007 arc seconds, which was sent into orbit from the Kennedy orbit Center aboard the space shuttle Discovery, is about comparable to focusing a laser beam on Franklin D. Roosevelt's head from a distance of 200 miles.  
  


3. Voyager Probes (Voyager 1 and Voyager 2):
 
The Voyager 1 and 2 missions are truly remarkable achievements in space exploration.They started their ambitious voyage in 1977, and since then, they have given us a wealth of scientific knowledge and iconic pictures of our solar system.

Voyager 1 and 2 made groundbreaking discoveries, including identifying active volcanoes on Jupiter's moon Io and discovering 22 moons across the outer planets. Voyager 2 also extended its mission to photograph Uranus and Neptune.

These spacecraft have ventured into interstellar space, a first for any human-made object, providing crucial data about the distant solar system and interstellar conditions. Despite their vast distance from Earth, both Voyagers continue to transmit data back, offering insights into the space beyond.

Carrying a golden record with scenes, sounds, music, and greetings from Earth, the Voyager spacecraft aim to provide a glimpse of our world to any potential extraterrestrial civilizations that may encounter them in the future. They are expected to continue their journey, passing other stars over thousands of years, enriching our understanding of the cosmos.

4. Mars Helicopter (Ingenuity):

The Perseverance rover's Ingenuity drone, a miniature helicopter, shows that powered flight is possible in the tenuous Martian atmosphere.



5. Satellites for Earth Observation:

Many satellites circle Earth and gather data for a variety of purposes, including communications, environmental monitoring, and weather forecasting. The GOES satellites and the Landsat series are two examples.


6.Parker Solar Probe


The Parker Solar Probe is a groundbreaking NASA mission launched on August 12, 2018, designed to study the Sun up close and unlock the mysteries of the solar corona. Here are some key highlights about this remarkable mission:

a) Closest Approach to the Sun:
    The Parker Solar Probe's mission involves swooping within approximately 4 million miles of the Sun's surface, enduring intense heat and radiation.

b) Mission Objective:
     The Parker Solar Probe's main objective is to research the solar corona in order to comprehend solar activity and phenomena, such as the solar wind and magnetic fields, which have an influence on Earth's technology and space weather.

c) Significance of Solar Wind:
    Eugene Parker, after whom the mission was named, theorized the existence of the solar wind in the 1950s, revolutionizing our understanding of the Sun's behavior and its influence on the solar system.

d) Understanding the Solar Corona:
      The Parker Solar Probe seeks to understand why the Sun's outermost layer, the solar corona, is hotter than its surface, defying accepted physics.

e) Historical Naming:
    Because of Eugene Parker's groundbreaking work in solar physics, the Parker Solar Probe is the first NASA mission to bear his name.

f) Legacy of Eugene Parker:
    We continue to learn more about the Sun thanks to Eugene Parker's theories and contributions to solar physics, which also influence space exploration and study.

g) Scientific Contributions:
     We will be able to predict and lessen the effects of important space-weather events on technology and life on Earth thanks in large part to the data gathered by the Parker Solar Probe.

h) Tribute to Eugene Parker:
  The Parker Solar Probe became the first NASA mission to be named after a living individual, reflecting Eugene Parker's unparalleled contributions to solar physics. 
Parker sadly passed away in March 2022 at the age of 94, leaving behind a significant legacy in the fields of astrophysics and space travel.

Unveiling the secrets of Voyager 1: Earth's farthest spacecraft

 Voyager 1: Earth's Farthest Spacecraft







Voyager 1 is the first spacecraft to attain interstellar space. It at the start used to be launched (along with Voyager 2) in 1977 to discover the outer planets in our solar system. However, it has remained operational lengthy previous expectations and continues to send data about its journeys lower back to Earth.


The spacecraft formally entered interstellar space in August 2012, nearly 35 years after its voyage began. The discovery wasn't made authentic till 2013, however, when scientists had time to overview the records despatched back from Voyager 1.



Voyager 1 used to be really the 2d of the twin spacecraft to launch, however it was once the first to race via Jupiter and Saturn. The pics it despatched back have been used in schoolbooks and newspaper retailers for a generation. Also on board was once a special record, carrying voices and tune from Earth out into the cosmos.


Voyager 2 launched on Aug. 20, 1977, and Voyager 1 launched about two weeks later, on Sept. 5. Since then, the spacecraft have been touring alongside specific flight paths and at unique speeds. The Voyager missions have been supposed to take benefit of a different alignment of the outer planets that occurs each 176 years. It would enable a spacecraft to slingshot from one planet to the next, assisted with the aid of the first planet's gravity. 


The spacecraft’s subsequent huge encounter will take region in 40,000 years, when Voyager 1 comes inside 1.7 light-years of the star AC +79 3888. (The star itself is roughly 17.5 light-years from Earth.) However, Voyager 1's falling power supply ability it will quit transmitting records through about 2025, which means no records will flow back from that far away location.


NASA firstly deliberate to send two spacecraft previous Jupiter, Saturn and Pluto and two different probes previous Jupiter, Uranus and Neptune. Budgetary motives pressured the organisation to scale again its plans, however NASA still received a lot out of the two Voyagers it launched. Voyager two flew previous Jupiter, Saturn, Uranus and Neptune, while Voyager 1 targeted on Jupiter and Saturn.


Recognizing that the Voyagers would fly out of the solar system, NASA licensed the manufacturing of two records to be positioned on board the spacecraft. Sounds ranging from whale calls to the tune of Chuck Berry had been positioned on board, as nicely as spoken greetings in 55 languages.



The 12-inch, gold-plated copper disks additionally protected pictorials displaying how to function it, and the function of the solar amongst close by pulsars in case extraterrestrials have been questioning the place the spacecraft got here from. 




Firsts :

  • Voyager 1 The first spacecraft to penetrate the heliosphere, when solar system forces from beyond our solar system outweigh those from our Sun, was Voyager 1.

  • The first artificial object created by humans to travel into interstellar space is Voyager 1.
  • Voyager 1 discovered a thin ring around Jupiter and two new Jovian moons: Thebe and Metis.
  • At Saturn, Voyager 1 found five new moons and a new ring called the G-ring.

Voyager 1's Pale Blue Dot


A picture of Earth obtained from NASA's Voyager 1 on February 14, 1990, at a distance of 3.7 billion miles (6 billion kilometers) from the Sun is known as The Pale Blue Dot. Look at that dot again. That dot is what gave the title of Carl Sagan's book, "Pale Blue Dot: A Vision of the Human Future in Space," its inspiration.

 That's home. That's us."


VOYAGER 1 JUPITER FLYBY



Voyager 1's closest approach to Jupiter occurred March 5, 1979. Voyager 2's closest approach was July 9, 1979.

When photography of Jupiter started in January 1979, the planet's brilliant bands were already better than anything seen from Earth. Early in April, Voyager 1 concluded its close encounter with Jupiter, capturing about 19,000 images and doing several other scientific observations. After taking up the mantle in late April, Voyager 2's encounter lasted until August. Over thirty thousand images of Jupiter and its five main satellites were captured.


Although astronomers had studied Jupiter from Earth for several centuries, scientists were surprised by many of Voyager 1 and 2's findings. They now understand that important physical, geological, and atmospheric processes go on - in the planet, its satellites, and magnetosphere - that were new to observers.

Most likely the biggest surprise was the discovery of active volcanism on the satellite Io. For the first time, active volcanoes were observed on a solar system world other than Earth. It seems that the Jovian system as a whole is impacted by activities on Io. The main source of stuff that seems to permeate the Jovian magnetosphere—the area of space surrounding the planet that is mostly affected by the planet's strong magnetic field—appears to be Io. At the outer border of the magnetosphere, sulfur, oxygen, and sodium were found. These elements seemed to have erupted from Io's volcanoes and spat off the surface due to the impact of high-energy particles.

VOYAGER 1 VISITS SATURN AND ITS MOONS


Scientists only had to wait about a year, until 1980, to get close-up pictures of Saturn. Like Jupiter, the ringed planet turned out to be full of surprises.

The F ring, a tiny structure first found by NASA's Pioneer 11 mission the year before, was one of Voyager 1's goals. Two additional moons, Prometheus and Pandora, were discovered by Voyager's higher-resolution camera. Their orbits maintain the frozen material in the F ring in a well-defined path. It also acquired pictures of many other Saturnian moons in addition to Atlas and the newly found G ring.


Titan, the solar system's second-largest moon (after Jupiter's Ganymede), posed a challenge to astronomers. Depictions of Titan up close revealed nothing but orange haze, sparking years of conjecture about what may be underneath. Humanity wouldn't learn until the middle of the 2000s, thanks to images taken by the European Space Agency's Huygens atmospheric mission from beneath the haze.


The Saturn encounter marked the end of Voyager 1's primary mission. The focus then shifted to tracking the 1,590-pound (720 kg) craft as it sped toward interstellar space.

Two decades before it notched that milestone, however, Voyager 1 took one of the most iconic photos in spaceflight history. On Feb. 14, 1990, the probe turned back toward Earth and snapped an image of its home planet from 3.7 billion miles (6 billion km) away. The photo shows Earth as a tiny dot suspended in a ray of sunlight. 

Voyager 1 took dozens of other photos that day, capturing five other planets and the sun in a multi-image "solar system family portrait." But the Pale Blue Dot picture stands out, reminding us that Earth is a small outpost of life in an incomprehensibly vast universe.
