Yes, Mars will be visible in the morning during the month of August.
Mars is always visible in the night sky and can be seen with the naked eye when it is above the horizon. Its visibility depends on its position in its orbit relative to Earth and can vary throughout the year. Astronomical apps or websites can help you track when Mars will be visible in your location.
Mars is visible to the naked eye nearly every night. It will be in the constellation Virgo. Mars will be quite distant and rather dim in late August, appearing less than half its average size. It will have about 1/10 of the brightness of last January because of its extreme distance this late summer and fall.
It depends where you are.
In August 2010, the planets Venus, Mars and Saturn are visible low in the west at sunset, while the planet Jupiter rises in the east at about 9 PM.
Around midnight
Yes. Mars will be visible low in the Eastern sky starting about 2 hours before dawn. But Mars will NEVER look "as big as the full moon!" as the Mars Hoax insists. Sorry; it won't happen.
I first heard of Bruno Mars in August or September, 2010
No. Mars did make an exceptionally close approach to Earth in August 2003, and every year since, spammers change the date and resend the message. However, Mars will NEVER appear "as big as the full Moon". Right now, on August 9, 2009, Mars rises a little before sunrise and is visible low in the eastern sky at dawn. By January, 2010, Mars will be overhead at midnight, but this will be one of the more distant conjunctions.
Around September 1, as seen from London, Mars is setting almost simultaneously with the sun, and is also drawing closer to the sun each day/night. Seen from the UK, the situation won't improve much until perhaps late July or early August 2011. By then, Mars will have pulled out in front of the sun sufficiently that it will begin to be visible in the eastern sky before the sun rises. This situation not only exists for the UK but world wide. If Mars isn't visible from the UK then it isn't visible in Australia either.
the brightest object is Venus, and mars is just barely south and above it.
Yes. In early August, look for Mars to rise about 2:30 AM, and be about 35 degrees above the eastern horizon at dawn. Mars will rise earlier and earlier throughout the month, rising about 1:30 AM by the end of August.
